NAME

integer - Perl pragma to compute arithmetic in integer instead of double

SYNOPSIS

    use integer;
    $x = 10/3;
    # $x is now 3, not 3.33333333333333333

DESCRIPTION

This tells the compiler that it's okay to use integer operations from here to the end of the enclosing BLOCK. On many machines, this doesn't matter a great deal for most computations, but on those without floating point hardware, it can make a big difference.
